- Aiiiypiiaanm nica august is, ieio. suini in. 577,001. To all whom 'itma/y conem: i This brake consists of a downwardly ex` Be it known that I, Pemex McCann', a citizen of the United States of America, residing at Honesdale, Wayne county, State of Pennsylvania, have invented a new and useful Tricycle, of which the following is a specification.

This invention relates to a new and useful l tricycle.

The main feature of the invention 1s-the provision of a novel steering mechanism com rising pairs of horizontally arranged osc` ating bars, connected in order to act in unison and connected with the front axle of that ,the tricycle may be readily steered by the handle bars. The verticall arranged shafts on which .the

airs o horizontally arrangedbscillating Ears are journaled are'mounted in bearings 20 on the elon ated portion of the frame of the machine. he'bars of each pair of the horizontally arranged oscillating bars are connected so that they will inoveas one body.

In the drawings Figure 1 is a erspece Varlsectional view taken through the handle bars and a pair of the horizontally arranged oscillating bars in order to show the detail Fig. 3 is a detail sectional view through the front bearing forthe shaft showing the bars 36.

As to the accom anying illustrations, 1 denotes the frame o the tricycle or machine 35 which com rises, at its forward portion, an

elongated eam 2 ,which terminates at the rear of the machine in a forked portion consisting of the side bars 3 and 4. J ournaled in bearings of the side bars 3 vand 4 1s a crank shaft or axle 6 and connected to the cranks of which are the links or pitman rods 7. Pivotally connected to the lower extremities ofthe links or pitman rods are the bifurcated ends 9 of the operating pedal bars 10. Journaled upon and designed to rotate with the crank shaft or axle is the driving wheel 11 whichcomprises the usual hub portion'13 and the rim 14, surrounding which is `the usual form `of pneumatic tire 15. In a pearance and construction this driving w eel is similar to bicycle wheels. The side bars 3 and 4 at the point where they merge into the elongated forward lower bar 2 are provided with upwardly extending portions 16 in which bearings 17 are provided for the pivots of the gravitation brake.

right ang ed portion 21 ofthe ivot bar 22.

The pedal ars are provide with broad pedals 24:' inI order that the operator may stand upon the same and by pressing first on one and then on the yother cause the ma-' chine to be propelled forward through the cranking mechanism. The forward ends 25 of the edal bars are provided with .elonated s ots 26 to receive the endsA of the caring bai' 29. To hold the ends of the edal ars upon the journals of the bearing ar, nuts 31 are threaded to the bearing bar at each end thereof.

Arran ed above the forward elongated bar of t e frame is an additional. bar 32, which is arran ed approximately parallel with the lower ar 2 and between the bar 32 and the bar 2 connections`33 are formed, which are brazed to the bar 2 and the bar 32. Journaled in bearings 34, 34, and 34h of the bars 2 and 32 are vertically arranged shafts 35 and 35. On the shaft 35 is a pair of horizontally ari-an ed oscillating bars or i beams 36, while on t e shaft 35 is a single bar 36. The bars 36 are properly spaced apart to' receive the connecting pitman, rods 37, which are connected to the beams by means of suitable bolts or other means 38. The rear ends of the rods 37 are connected to the outer ends of the single bar 36, as at 38. The rear shaft 35 is provided with the shoulder 35, and adjoining the shoulder is a rectan ylar portion 35", on which is fitted the rear ar 36. Threaded on the rear shaft 35 is a nut 35, which holds the rear bar 36 against the shoulder. AThe forward shaft 35 is provided with a rectangular portion 35, and above and below this portion, the shaft 35 is threaded, as shown at 35. Fitted on the rectangular portion 35 is a member 35, which is provided with upper and lower lugs 35s at each end, between which the forward bars 36 are arranged. These lugs constitute means together with the rectween the lugs. l

portion is provided with a collar a, which is tangular portion 35d, to cause the forward bars 36I to rock with the 'forward shaft 35. Nuts 35k are threaded -on the shaf't35q, to hold the forward bars 36q in position be- 'Ihe shaft 35c1 near its base secured to the'shaft by thepin b. The shaft 35q extends through the casing c, 1n the upper and lower portions of which the ball bearings 34h are arran ed. These ball bearings are held in place the plugs d and f, which are threaded'in t, e'casmg c. By this arrangement, it will be seen that vertical the same is permitted .to freely turn.

shaft 35q extends from an enlargement of the axle shaft 40. The shaft 35 extends through a casing g, in which the ball bearings 34 ,are mounted, in the top and the bottom thereof. Collars It, one secured ii1`each end of the casing g, to hold-the balls in place, are provided; Arranged between the collars h and the lock nuts la, which are threaded to the flanges m, are packing rings n. The lock nuts k are for the purpose of lockingy the nuts p in place as will be seen clearly in Fig. 2. It willbe clearly noted that by these ball bearings and the thrust bearing of the shaft v35, the same may readrai'sed slightly from its thrust bearing, but not suiliciently` to remove the lower end of the shaft 35 completelyv from the socket of the thrust bearing. It has been found that these forms of ball bearin mountmgs are especially adaptable, desira le and essential to this form o steerin mechanism, for this design of steering mec anism may not onl be applied to a tricycle, but equally as We to automobiles and the like, and also tosled trucks and the'like, whereby the sled truck may be guided by the party at the rear. These horizontally arranged oscillating bars 36q are fixed with. regard to one another so as to move as one body when the steering mechanism ismanipulated through the handle bars 39. The forward verticallyV ar- Y ranged shaft is connected to the lforward axle shaft 40 so that the two may move toether and journaled upon the trunnions of t eforward axle shaftare the usual -wheels 41. These -wh ls l41 are of the same make and type as the driving wheel in the rear of the machine, comprisin the usual hub l43, the rim 44 and the usua form of pneumatic tire 45. The wheels 41 are rovided with ball bearings 47 where the w eels are journaled upon the trunnions of the front shaft or axle.

Arranged above the driving wheel is a seat 48 similar to the ordinary bicycle seat.

The operator of this machine is supposed tostand when manipulating the pedal bars,

` but he may, in coasting, use the seat and rest his feet upon the frame of the machine.

movement of the shaft35q is prevented, rlylt e ily turn, and not only turn but mayy be The entire frame of the machine is designed to be made of drawn tubular material and all joints vof the frame are designed to be brazed. as is usually the case in the construction of bicycle frames and similar devices.
